Abstract

Cloud computing systems use shared resources that are naturally susceptible to exploitation, “denial-of-service (DoS)” and “distributed denial-of-service (DDoS)” attacks continue to represent serious dangers. Therefore, to protect cloud infrastructures from these risks, resource isolation becomes an essential tool. This study gives a thorough analysis of resource isolation methods for preventing “DoS” and “DDoS” assaults in cloud computing. The research examines the resource isolation tactics, including virtualization, containerization, RSA token-based access and software-defined networking, which helps in establishing strong boundaries between the resources used by the multiple cloud tenants and also aims to stop those traffics that are meant to cause the DoS/DDoS attacks and thereby preventing vital cloud resources. Considering the dynamic nature of the cloud environment, I have also evaluated each technique's impact in terms of security, performance, and implementation overhead. This study intends to assist cloud service providers in making choices to strengthen their defensive mechanisms against “DoS” and “DDoS” attacks using resource isolation and thereby assuring the continuous and safe operation of cloud-based services.
